中医综合疗法治疗泄泻的护理干预

目的探讨中医综合疗法治疗泄泻的护理干预效果。方法随机选取我科住院的60例泄泻患者,根据辨证分型给予口服辨证汤药联合针刺、艾灸以及耳穴压豆外治的中医综合疗法治疗,并对所有患者给予相应的护理干预。结果60例患者症状在较短的时间内得到恢复,痊愈43例(71.7%),显效15例(25.0%),有效2例(3.3%),无效0例(0.0%),总有效率达100.0%。结论对泄泻患者采用中医综合疗法治疗的同时进行护理干预,能够提高患者的依从性,更快的解除患者的痛苦。     

建设世界科技强国背景下科技人才职业满意度指标筛选方法与测评模型研究

科技人才研究是围绕建设世界科技强国开展的一项基础性研究工作,科技人才职业满意度状况探索更是激发科技人才积极性、推动经济社会发展的重要课题。面临科技人才职业满意度研究可能存在指标数量较多、指标含义重复等问题,本文基于人才学相关理论,首先讨论科技人才职业满意度测评指标体系,然后提出先借助对职业满意度测评指标进行筛选、再对筛选前后的指标体系分别构建职业满意度测评模型的方法和思路,以期为全面评价我国科技人才职业满意度、挖掘关键影响因素提供参考。     

Dynamic Price Competition with Consumption Externalities

The dynamic price competition in a horizontally differentiated duopoly when consumers value previous market shares is analyzed. The conditions for the existence of stable Markov-Perfect Equilibrium (MPE) in linear strategies are established. When they exist, the optimal pricing policies suggest that a firm with a higher previous market share charges a higher price, all else equal. It is possible to observe pricing below cost for some periods. In the steady state, the MPE leads to a more competitive outcome (lower prices) than the case where there are no consumption externalities. The model can produce outcomes where the steady state is reached very slowly which provides an alternative explanation for slow emergence of competition when entrants face an established incumbent: It may be due to persistence in consumer tastes.

A nested logit model of strategic promotion

This paper presents a test of the nature of the pricing and promotion game played by supermarket retailers in a large, U.S. market. Using a nested-logit modeling approach, the results show that retailers set discount depth and promotional frequency in a manner that is less competitive than Bertrand. We also find that the elasticity of substitution among competing stores is lower than among products within each store, but not equal to zero. Therefore, sales do cannibalize existing products, but can also build a significant amount of store-traffic. Relative to strategic factors, price promotions have their greatest impact on store-conditional product demand.

深圳城市品牌定位浅析

正确的城市品牌定位能为城市创造巨大的财富,增强城市的凝聚力、向心力、吸引力和辐射力。深圳作为改革开放的前沿城市,其发展备受瞩目,而城市品牌定位却一直没有统一的尴尬现状影响到了深圳的进一步发展。高科技产业成为深圳市的第一产业,结合这一实际情况,深圳城市品牌应定位为"中国的科技中心"。深圳可以通过广告宣传和公共关系专题活动积极推广城市品牌定位,在公众心中树立深圳是中国的科技中心的观念。

垄断市场中双寡头企业的市场行为研究\n——从产品纵向差异的角度分析

从产品纵向差异的角度分析了垄断市场中双寡头企业的短期市场行为和长期市场行为.具体来说,从短期的角度出发,将产品质量视为外生变量,研究高质量企业和低质量企业的定价策略和利润状况,并对均衡结果进行比较静态分析.研究结果表明,两个企业都有提高或降低各自产品质量的动机,这取决于双方现有的质量水平.从长期的角度出发,将产品质量视为内生变量,研究企业的质量与价格决策.研究结果表明,产品质量存在唯一均衡,但均衡质量并没有表现出较大的差异化,而是表现出较小的差异化.此外,无论从短期还是长期的角度来看,企业都不存在高质量优势,而仅存在低质量优势.     

Agglomeration, innovation and international research mobility

This paper discusses a model of the New Economic Geography, in which the seminal core-periphery model of Krugman [Krugman, P., 1991, Increasing returns and economic geography, Journal of Political Economy 99, 483–499.] is extended by endogenous research activities. Beyond the common ‘anonymous’ consideration of R&D expenditures within fixed costs, this model introduces in an analytically tractable approach vertical product differentiation in combination with a de-integrated R&D sector. In the context of international factor mobility, the destabilizing effects of a mobile scientific workforce are analyzed. Based upon a simple welfare analysis, a consideration of R&D promoting policy instruments and their spatial implications, this paper makes a contribution to the brain-drain debate.
